  • Patent number: 6665291
    Abstract: In a communications system comprising a public or other network (170), a wireless network (7), and an Internet Protocol based network (IP network) (100) configured as a transport mechanism between the public or other network (170) through a public network interface (160) and the wireless network (7) through a base station interface (140), a method of controlling signal traffic over multiple IP subnets, the method comprising the steps of gathering traffic data associated with the multiple IP subnets, and analyzing the traffic data to determine which of the multiple IP subnets provides the most appropriate connection for transmitting the data stream between the wireless network and the public or other network for achieving a desired amount of traffic distribution over the multiple IP subnets.

  • Patent number: 6256490
    Abstract: A telecommunications system and method is disclosed for providing a cell traffic supervision alarm within a base station (BS) to notify the operator at a Mobile Switching Center (MSC) serving the BS that the BS has had no traffic for a period of time that is unreasonably long. The definition of “unreasonably long” is tied to normal traffic patterns at the BS. An alarm threshold time, which is defined as time between the cessation of all traffic on a BS and the triggering of the alarm, can be calculated based upon a statistical analysis of the traffic history of the BS to determine a time interval such that the probability is acceptably small that under normal conditions the BS would have gone for that entire length of time with no traffic at all. At the expiration of the alarm threshold time, the alarm is activated.
